Auxiliary bracing structure for movable racks

ABSTRACT

An auxiliary bracing structure for movable racks includes a case, a lid and a movable rack. The lid corresponds to the case and may be coupled with the case to form substantially a closed housing compartment. The lid has a bracing strut mounted on an inner side. The movable rack is located in the housing compartment and has a slot corresponding to the bracing strut. The slot has a loading end with a diameter greater than the diameter of an anchor end of the slot. The bracing strut may run through the slot through the loading end and be moved to the anchor end for anchoring thereby to anchor the movable rack on the lid.

FIELD OF THE INVENTION

The present invention relates to an auxiliary bracing structure adoptedfor use on the case of an electronic device to brace one end of amovable rack that is not fastened to the case.

BACKGROUND OF THE INVENTION

The conventional movable rack located in the case of electronic devicesusually have one end fastened to the case by coupling screws with screwholes. The movable rack has another end not being fastened. Theunfastened end tends to sag under heavy weight. Later on there was adesign using hand-driven screws to fasten the other end on the case.Such a design is too complicated and difficult to assemble, and tootime-consuming.

Further, another approach is developed that saddles the unfastened endover a transverse beam on the case. While it can prevent sagging, it ismore costly, and also affects space and wiring configuration of thecase.

All the schemes set forth above are not desirable. There is a need todevelop an improvement to resolve those disadvantages.

SUMMARY OF THE INVENTION

Therefore, the primary object of the present invention is to provide anauxiliary bracing structure for movable racks to prevent the unfastenedend of a movable rack from sagging under heavy weight, and to save costsand space without affecting wiring configuration.

The auxiliary bracing structure for movable racks according to theinvention includes a case, a lid and a movable rack. The lid correspondsto the case and can be coupled with the case to form a substantiallyclosed housing compartment. The lid has a bracing strut mounted on aninner side. The movable rack is located in the housing compartment andhas a slot corresponding to the bracing strut. The slot has a loadingend with a diameter lager than the diameter of an anchor end thereof.The bracing strut can run through the slot through the loading end andbe moved to the anchor end to anchor the movable rack on the lid.

When the case and the lid are coupled, dispose the lid in such a waythat the bracing strut runs through the loading end of the slot of themovable rack. Move the lid to slide the bracing strut into the anchorend so that the lid can provide bracing-assisted support for the movablerack.

The foregoing, as well as additional objects, features and advantages ofthe invention will be more readily apparent from the following detaileddescription, which proceeds with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

When a movable rack 30 is located in a case of an electronic device, ithas one end fastened to the case 10 (referring to FIG. 4) and anotherend not fastened to the case 10. As a result, the another end of themovable rack 30 often sags under the heavy weight.

Refer to FIG. 1 for the bracing strut, FIG. 2 for the lid, and FIG. 3for the movable rack. The auxiliary bracing structure for movable racksaccording to the invention includes a case 10, a lid 20 and a movablerack 30.

The lid 20 corresponds to the case 10 and can be coupled with the case10 to form a substantially closed housing compartment. The lid 20 has abracing strut 21 mounted on an inner side by riveting. The bracing strut21 has an anchor groove 211.

The movable rack 30 is located in the housing compartment. It has a slot31 corresponding to the strut 21. The slot 31 has a loading end 311,which has a diameter greater than the diameter of an anchor end 312 ofthe slot. The loading end 311 further has an assisted coupling member313 which helps the lid 20 to maintain at a desired elevation to assistthe lid 20 to couple with the movable rack 30. The anchor end 312corresponds to the anchor groove 211. The bracing strut 21 can runthrough the slot 31 through the loading end 311 and be moved to theanchor end 312 to be anchored thereby, to anchor the movable rack 30 onthe lid 30.

Referring to FIGS. 4 and 5, when the case 10 and the lid 20 are coupledtogether, the bracing strut 21 of the lid 20 runs through the loadingend 311 of the slot 31 of the movable rack 30. First the bracing strut21 is rested on the assisted coupling member 313 to maintain the lid 20at a desired elevation. Then the lid 20 can be moved such, that theanchor groove 211 of the bracing strut 21 slides into the anchor end312. Thereby, the lid 20 can provide bracing-assisted support for themovable rack 30.

Of course, the number of bracing struts 21 and slots 31, and thelocations of the bracing strut 21 and the slot 31 relative to themovable rack 30 may be altered according to requirements, to enhance thebracing-assisted function of the lid 20 to the movable rack 30.

By means of the invention, the unfastened end of the movable rack 30 inthe case 10 has proper support without sagging. It also saves costs andspace, and does not affect the wiring configuration.

While the preferred embodiment of the invention has been set forth forthe purpose of disclosure, modifications of the disclosed embodiment ofthe invention as well as other embodiments thereof may occur to thoseskilled in the art. Accordingly, the appended claims are intended tocover all embodiments, which do not depart from the spirit and scope ofthe invention.
